Its been two year since then I am using hitachi air conditioner. The first year was fine the service people came from the company and gave their services as it was under guarantee. After one year got over and I want to get the AC serviced by the company it was such a bad experience I tell you. I called on their customer care number, left an email, had a chat on their website but no body turned up I was shocked with the response I was getting with these people. I would not suggest any one to buy hitachi as their after sale service is very poor you will be just stuck in my case no body turned up from the company at the end I have to get it done by an outside engineer.
